Beat me to it Mart. Missouri does have a brand database but can't find it online. The State does have laws and a database. Lots of states you can find them and the meaning of brands, how to read them (top to bottom, inside to out, outside to in, side to side, pictures, letters, numbers, a combination, whether they are Freeze brands or Hot Iron Brands.) There is alot to it...and very interesting.
FYI....did you know that the first known brands were in Egypt (2000BC). But it has been argued that it started in Sweden in the middle age (476-1492) and spread by the Vikings to England. So, it's not just here in Texas!!!! Today we have patents and registrations whereas it all started as Brands/Branding! (Identification 101 Class! LOL)
